ATOS piston pumps are an important component of hydraulic systems. They rely on the reciprocating motion of the piston within the cylinder to change the volume of the sealed working chamber, thus achieving oil suction and pressure. ATOS piston pumps offer advantages such as high rated pressure, compact structure, high efficiency, and convenient flow regulation, and are widely used in high-pressure, high-flow, and flow-regulating applications, such as hydraulic presses, construction machinery, and ships.

The Italian ATOS piston pump is a type of reciprocating pump, belonging to the category of volumetric pumps. Its piston is driven by the eccentric rotation of the pump shaft, reciprocating in motion. Both its suction and discharge valves are one-way valves. When the piston is pulled outward, the pressure in the working chamber decreases, the outlet valve closes, and when the pressure is lower than the inlet pressure, the inlet valve opens, allowing liquid to enter. When the piston is pushed inward, the pressure in the working chamber increases, the inlet valve closes, and when the pressure is higher than the outlet pressure, the outlet valve opens, allowing liquid to exit. When the drive shaft rotates the cylinder block, the swashplate pulls the plunger out or pushes it back into the cylinder block, completing the oil suction and discharge process. The oil in the working chamber formed by the plunger and cylinder bore communicates with the pump's suction and discharge chambers via a distribution plate. The variable displacement mechanism is used to change the swashplate's tilt angle; adjusting the swashplate's tilt angle changes the pump's displacement.

The output pressure of an ATOS piston pump is determined by the load and is approximately proportional to the input torque. There are two types of abnormal output pressure:

(1) Low output pressure

When the Italian ATOS piston pump is in self-priming mode, if there is air leakage in the inlet line or significant leakage in the hydraulic cylinder, check valve, or directional valve in the system, the pressure will not rise. This requires finding the leak, tightening, or replacing the seals to increase the pressure. If the relief valve is faulty or the adjusted pressure is too low, and the system pressure cannot rise, the pressure should be readjusted or the relief valve should be repaired. If the cylinder body and distributor plate of the Italian ATOS hydraulic pump are misaligned, causing significant leakage, and in severe cases, the cylinder body may crack, the mating surfaces should be re-ground or the hydraulic pump should be replaced.

(2) Excessive Output Pressure

If the circuit load of the Italian ATOS piston pump continues to increase, the pump pressure will also continue to increase, which is normal. If the load is constant and the pump pressure exceeds the pressure value required by the load, hydraulic components other than the pump should be checked, such as directional valves, pressure valves, transmission devices, and return lines. If the maximum pressure is too high, the relief valve should be adjusted. The company mainly deals with European and American brands and can source brands from any European country.
